As is evident from the letter quoted above, Huxley was a passionate defender of Darwin's theory -- so passionate that he has been called "Darwin's Bulldog". But Huxley was not only the bulldog for Darwin's theory, but was a great biologist in his own right, who did original research in zoology and paleontology.

It took a little bit of finding, as I could not find it print in any major bookstore either on the high street or online. Eventually, I managed to get my hands on a second hand book. The cover is a bit, well, utilitarian.
Lynn Margulis disses evolution in Discover magazine, embarrasses both herself and the field. Around 1970, biologist Lynn Margulis achieved renown for suggesting, and then showing, that eukaryotic cells originated by a symbiotic union of early prokaryotes, with some engulfing others and then the engulfed bacteria evolving into at least two of the cell’s vital organelles: mitochondria and (in plants) chloroplasts.

Although others had suggested this before, Margulis gets the credit for pushing the theory forward, supporting it with biochemical and microbiological data, and recognizing its implications. Later work on DNA sequencing supported her completely. She became famous and was elected to the National Academy of Sciences. To reword the old political slogan for science: fame corrupts, and huge fame corrupts hugely. This isn’t always true, but if a scientist achieves tremendous fame and adulation, there’s always the temptation to think that what you say on every topic bears special weight and consideration.

Hoje, já ninguém se ri: ela tinha razão.
Lynn Margulis, Neo-Darwinism, And Kin Selection. Professor Lynn Margulis is the biologist who had the incredible insight that the cells of modern organisms were originally formed by the symbiotic combination of prokaryotic cells and colonies of bacteria, and then had to battle for years to have this recognised by the science community.

The idea is so outlandish, but so significant, that it puts her right up there as one of the greats of biology.

Lynn Margulis, Biological Rebel - Scientific American Blog Network. The biologist Lynn Margulis died on November 22 at the age of 73.

I adapted the following essay about her from my 1996 book The End of Science. Lynn Margulis was among the most creative challengers of mainstream Darwinian thinking of the late 20th century. She challenged what she called "ultra-Darwinian orthodoxy" with several ideas. The first, and most successful, is the concept of symbiosis. Darwin and his heirs had always emphasized the role that competition between individuals and species played in evolution.

Margulis proposed that eukaryotes may have emerged when one prokaryote absorbed another, smaller one, which became the nucleus.

The best epitaph for Lynn Margulis probably consists of her own words, from a Discover magazine Q&A with her, published earlier this year: Q: Do you ever get tired of being called controversial?
A: I don’t consider my ideas controversial. I consider them right. George Dyson Science Historian, Author, Darwin Among the Machines; Turing's Cathedral (forthcoming)
Margulis-Dawkins Debate. The underground lecture hall of Balliol College in the University of Oxford was already full.

In fact, people were queuing all the way up the staircase, ears alert to hear the intellectual explosions as the two titans of evolutionary theory faced each other in debate. Richard Dawkins on one side, champion since writing The Selfish Gene in 1976 of the neo-Darwinist view that evolution happens via accumulation of random mutations in DNA, followed by natural selection.

Make a Sky Photo Calendar. A digital camera is ideal for making a daily record of sky color. A photographic record of sky color has real scientific value, especially if it covers a long period of time. For best results, each day photograph the same area of the sky at about the same time. When you save the photos in a computer, assign each one with its date. Save all your sky photos in a folder labeled with the year you made them. Tip: Try to use a camera with a time stamp feature that places the date and time on each photo.Related Picture Post Project 2. You can easily prove that the blue light in the flashlight beam is scattered more than the red light by following the beam of the flashlight as it travels through the milky water. You can use a white card to follow the beam from the flashlight side of the tray to the opposite side. Tip: An older flashlight with an incandescent bulb works better than a newer flashlight with a light-emitting diode (LED). 3.
